Abstract


Data integration of the first step is from the information source to extract data from the viewpoint of efficiency, and the amount of data transmission angle , the best method is to be able to promptly detect the incremental data of the information source . Classification of information source both databases and flat files . Choose the most suitable for the characteristics of the source of information and the needs of the operational level , the method can be captured from a variety of incremental . This article focuses on the study based on log analysis mode incremental capture method , it is dependent on the database and log system , I realized oracle database system log analysis . Paper summed up the first available information theoretical basis for research and tools to use Notes , which are based on I own practice . First described the log extraction effectiveness and incremental net effect of these two major problems , the log extract this is the critical foundation of the entire method , based on two analytical mode , running from the initialization and normal operation , interrupt restart three cases to illustrate the problems you might encounter , as well as ideas of how to solve the purpose is to reliably , efficiently extracted in accordance with the Service IDU operation of a specific object . The net effect of processing operations from within a transaction record exchangeable and simplify rules describe theoretical treatment model based on ideas to deal with difficult issues and solve different circumstances ; Secondly, the introduction of multi-source analysis , composite affairs concept , and some of the existing difficulties described , for example, the composite transaction control , multi-source operating transaction , etc.
